The expansion of quality ESG training and research programs is a powerful instrument to address the scarcity of adequately trained ESG experts. The latter constitutes a material risk to financial sector stakeholders who continue to rely mostly on existing financial specialists to cover ESG issues. The growing requirements for quality climate-aligned risk management, ESG factor integration, and non-financial reporting, assembling diverse teams of financial and environmental experts will be a determining factor in scaling sustainable finance and ESG activities across the entire sector. In order to respond to regulatory changes and avoid greenwashing, ESG specialists require vital non-financial skills that go beyond the consultation of ESG ratings of financial and products.
